I love CardDesk and would really not like to see it dying. I think there are 3 ways to go for you: 1. Just put everything you have on github and find people like me to make it better and donate for the hosting costs. 2. Make your own business out of it. Which is really hard with no time and in general with web services. 3. Find a way to make Evernote add CardDesk to Evernote!
